This is not a halal restaurant. It prints a supplier brand carrying the word halal on one American Wagyu cut, which describes that product line and not the kitchen. The restaurant itself makes no halal claim, no certifier is named, and the kitchen also handles pork and alcohol. If you need halal, treat this as a sourcing detail rather than a place to eat.

Common questions
- Does Mastro's Steakhouse - Santa Clara serve real Wagyu?
- Yes, and it says where the beef comes from. Mastro's Steakhouse - Santa Clara in Santa Clara, CA publishes enough detail on its own materials to identify the Wagyu it sells, which is the standard this directory calls verified, last checked on July 20, 2026. That means a named Japanese brand or prefecture with its grade, an American breed status with a named producer, or an Australian producer with a marbling score.
- What kind of Wagyu does Mastro's Steakhouse - Santa Clara serve?
- Its menu discloses Miyazaki A5, Kobe (Hyogo Prefecture) A5 and WinterFrost. Each of those is taken from the venue's own current materials rather than from a review or a listing site, and the evidence behind it is quoted further down this page.
- Is the Wagyu at Mastro's Steakhouse - Santa Clara Kobe beef?
- Yes, on both counts that matter. This venue appears on the official Kobe Beef Marketing and Distribution Promotion Association registry, and Kobe was on its verified menu when last checked on July 20, 2026. Both are required here: a registry listing alone is permission to buy Kobe, not proof that any is being served.
- How was Mastro's Steakhouse - Santa Clara verified?
- By reading the venue's own current material, its menu, its site or its ordering system, and quoting the line that names the beef. Reviews, aggregator copies and press mentions are not accepted as the source, because they go stale silently. Verification is assisted by AI and every claim is stored with the page it came from, last confirmed on July 20, 2026.
